I think we - the Perl community - have to overcome this (often wrong) moral attitude like shouting out "I'm using Perl and I'm proud of it." is dirty, unhonorable etc.

You may not care what the "world outside" thinks about Perl. But you should. If the world starts to think Perl is sh*t (and the majority of the IT-world has that impression - of course without having any facts for that opinion), Perl starts to loose traction. Attraction. To new, young, motivated and talented people.

If you try to step outside the Perl echo chamber (hard thing, I know), and imagine you are a programmer, considering what programming language to use for your next project. You would like to see how popular a language is, has been and probably will be. You will stumble across the TIOBE index. Currently it looks like this:
http://www.tiobe.com/index.php/paperinfo/tpci/Perl.html
Now if you would like to think THAT could attract anybody - you are most certainly out of your mind.

And because you are not, you see the necessity of action. Here, on CPAN, on Wikipedia and others where we can do something about it.
